2022-06-29dm raid: fix KASAN warning in raid5_add_disksMikulas Patocka
There's a KASAN warning in raid5_add_disk when running the LVM testsuite. The warning happens in the test lvconvert-raid-reshape-linear_to_raid6-single-type.sh. We fix the warning by verifying that rdev->saved_raid_disk is within limits.

Currently, the response to the power cap command overwrites the first eight bytes of the poll response, since the commands use the same buffer.

2022-06-30PM / devfreq: Rework freq_table to be local to devfreq structChristian Marangi
On a devfreq PROBE_DEFER, the freq_table in the driver profile struct, is never reset and may be leaved in an undefined state. This comes from the fact that we store the freq_table in the driver profile struct that is commonly defined as static and not reset on PROBE_DEFER. We currently skip the reinit of the freq_table if we found it's already defined since a driver may declare his own freq_table. This logic is flawed in the case devfreq core generate a freq_table, set it in the profile struct and then PROBE_DEFER, freeing the freq_table. In this case devfreq will found a NOT NULL freq_table that has been freed, skip the freq_table generation and probe the driver based on the wrong table. To fix this and correctly handle PROBE_DEFER, use a local freq_table and max_state in the devfreq struct and never modify the freq_table present in the profile struct if it does provide it.

The cpufreq passive unregister notifier is called both from the GOV_START errors and for the GOV_STOP and assume the notifier is successfully registred every time. With GOV_START failing it's wrong to loop over each possible CPU since the register path has failed for some CPU policy not ready.

2022-06-29xfs: dont treat rt extents beyond EOF as eofblocks to be clearedDarrick J. Wong
On a system with a realtime volume and a 28k realtime extent, generic/491 fails because the test opens a file on a frozen filesystem and closing it causes xfs_release -> xfs_can_free_eofblocks to mistakenly think that the the blocks of the realtime extent beyond EOF are posteof blocks to be freed. Realtime extents cannot be partially unmapped, so this is pointless. Worse yet, this triggers posteof cleanup, which stalls on a transaction allocation, which is why the test fails. Teach the predicate to account for realtime extents properly. Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Darrick J.

2022-06-29xfs: don't hold xattr leaf buffers across transaction rollsDarrick J. Wong
Now that we've established (again!) that empty xattr leaf buffers are ok, we no longer need to bhold them to transactions when we're creating new leaf blocks. Get rid of the entire mechanism, which should simplify the xattr code quite a bit. The original justification for using bhold here was to prevent the AIL from trying to write the empty leaf block into the fs during the brief time that we release the buffer lock. The reason for /that/ was to prevent recovery from tripping over the empty ondisk block. Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Darrick J. Wong <djwong@kernel.org>
2022-06-29xfs: empty xattr leaf header blocks are not corruptionDarrick J. Wong
TLDR: Revert commit 51e6104fdb95 ("xfs: detect empty attr leaf blocks in xfs_attr3_leaf_verify") because it was wrong. Every now and then we get a corruption report from the kernel or xfs_repair about empty leaf blocks in the extended attribute structure. We've long thought that these shouldn't be possible, but prior to 5.18 one would shake loose in the recoveryloop fstests about once a month. A new addition to the xattr leaf block verifier in 5.19-rc1 makes this happen every 7 minutes on my testing cloud. I added a ton of logging to detect any time we set the header count on an xattr leaf block to zero. This produced the following dmesg output on generic/388: XFS (sda4): ino 0x21fcbaf leaf 0x129bf78 hdcount==0! Call Trace: <TASK> dump_stack_lvl+0x34/0x44 xfs_attr3_leaf_create+0x187/0x230 xfs_attr_shortform_to_leaf+0xd1/0x2f0 xfs_attr_set_iter+0x73e/0xa90 xfs_xattri_finish_update+0x45/0x80 xfs_attr_finish_item+0x1b/0xd0 xfs_defer_finish_noroll+0x19c/0x770 __xfs_trans_commit+0x153/0x3e0 xfs_attr_set+0x36b/0x740 xfs_xattr_set+0x89/0xd0 __vfs_setxattr+0x67/0x80 __vfs_setxattr_noperm+0x6e/0x120 vfs_setxattr+0x97/0x180 setxattr+0x88/0xa0 path_setxattr+0xc3/0xe0 __x64_sys_setxattr+0x27/0x30 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x46/0xb0 So now we know that someone is creating empty xattr leaf blocks as part of converting a sf xattr structure into a leaf xattr structure. The conversion routine logs any existing sf attributes in the same transaction that creates the leaf block, so we know this is a setxattr to a file that has no attributes at all. Next, g/388 calls the shutdown ioctl and cycles the mount to trigger log recovery. I also augmented buffer item recovery to call ->verify_struct on any attr leaf blocks and complain if it finds a failure: XFS (sda4): Unmounting Filesystem XFS (sda4): Mounting V5 Filesystem XFS (sda4): Starting recovery (logdev: internal) XFS (sda4): xattr leaf daddr 0x129bf78 hdrcount == 0!

Unfortunately, it doesn't prevent the log from getting flushed to disk, which sets up log recovery to fail. So. It's clear that the kernel has always had the ability to persist attr leaf blocks with ichdr.count==0, which means that it's part of the ondisk format now. Unfortunately, this check has been added and removed multiple times throughout history. It first appeared in[1] kernel 3.10 as part of the early V5 format patches. The check was later discovered to break log recovery and hence disabled[2] during log recovery in kernel 4.10. Simultaneously, the check was added[3] to xfs_repair 4.9.0 to try to weed out the empty leaf blocks. This was still not correct because log recovery would recover an empty attr leaf block successfully only for regular xattr operations to trip over the empty block during of the block during regular operation. Therefore, the check was removed entirely[4] in kernel 5.7 but removal of the xfs_repair check was forgotten. The continued complaints from xfs_repair lead to us mistakenly re-adding[5] the verifier check for kernel 5.19. Remove it once again.

2022-06-29nvme-tcp: always fail a request when sending it failedSagi Grimberg
queue stoppage and inflight requests cancellation is fully fenced from io_work and thus failing a request from this context. Hence we don't need to try to guess from the socket retcode if this failure is because the queue is about to be torn down or not. We are perfectly safe to just fail it, the request will not be cancelled later on.

2022-06-29nvmet-tcp: fix regression in data_digest calculationSagi Grimberg
Data digest calculation iterates over command mapped iovec. However since commit bac04454ef9f we unmap the iovec before we handle the data digest, and since commit 69b85e1f1d1d we clear nr_mapped when we unmap the iov. Instead of open-coding the command iov traversal, simply call crypto_ahash_digest with the command sg that is already allocated (we already do that for the send path). Rename nvmet_tcp_send_ddgst to nvmet_tcp_calc_ddgst and call it from send and recv paths.

Trying to build a .c file that includes <linux/bpf_perf_event.h>: $ cat test_bpf_headers.c #include <linux/bpf_perf_event.h> throws the below error: /usr/include/linux/bpf_perf_event.h:14:28: error: field ‘regs’ has incomplete type 14 | bpf_user_pt_regs_t regs; | ^~~~ This is because we typedef bpf_user_pt_regs_t to 'struct user_pt_regs' in arch/powerpc/include/uaps/asm/bpf_perf_event.h, but 'struct user_pt_regs' is not exposed to userspace. Powerpc has both pt_regs and user_pt_regs structures. However, unlike arm64 and s390, we expose user_pt_regs to userspace as just 'pt_regs'. As such, we should typedef bpf_user_pt_regs_t to 'struct pt_regs' for userspace. Within the kernel though, we want to typedef bpf_user_pt_regs_t to 'struct user_pt_regs'. Remove arch/powerpc/include/uapi/asm/bpf_perf_event.h so that the uapi/asm-generic version of the header is exposed to userspace. Introduce arch/powerpc/include/asm/bpf_perf_event.h so that we can typedef bpf_user_pt_regs_t to 'struct user_pt_regs' for use within the kernel. Note that this was not showing up with the bpf selftest build since tools/include/uapi/asm/bpf_perf_event.h didn't include the powerpc variant.

2022-06-29fbdev: Disable sysfb device registration when removing conflicting FBsJavier Martinez Canillas
The platform devices registered by sysfb match with firmware-based DRM or fbdev drivers, that are used to have early graphics using a framebuffer provided by the system firmware. DRM or fbdev drivers later are probed and remove conflicting framebuffers, leading to these platform devices for generic drivers to be unregistered. But the current solution has a race, since the sysfb_init() function could be called after a DRM or fbdev driver is probed and request to unregister the devices for drivers with conflicting framebuffes. To prevent this, disable any future sysfb platform device registration by calling sysfb_disable(), if a driver requests to remove the conflicting framebuffers.
